TLDR; Use the following to completely destroy all your iOS Simulators and to create a new batch.

While trying out the new Xcode 7 beta’s, this happened to me… a lot…
Love this extremely concise and clear list of iOS Simulators. #Xcode pic.twitter.com/trYIa9hBcP

Looks like the different Xcode’s have varying ideas about when to install new devices and just go for safe. If you install a lot of new beta’s, this might look familiar to you.
While searching for the solution I came across the command line tool and options:
> xcrun simctl list
> xcrun simctl delete <device>
> xcrun simctl create <name> <device type id> <runtime id>
Using some regex witchcraft, I placed the entire list of device UUIDs in a file and deleted all my simulators and installed a couple of new ones. And of course, I vowed to create a script to avoid having to do this manually again.
Instead, I got the following tweet a while later;
Thanks @miguelcabeca for https://t.co/blruwarSo9! I finally have a nice list of simulators again. (cc @brunoscheele) pic.twitter.com/SxxuOqYnbk

@miguelcabeca has gifted us with this wonderfull little script;
Save that somewhere, make it executable and run it. You’ll have a nice clean list of iOS Simulators once more!
